America’s desire to expand its borders has existed since its first colonies – from attempts to settle beyond the Appalachian Mountains in the 18th century to Manifest Destiny in the 19th century down to talks today to purchase Greenland.  But the United States spent two centuries eyeing acquisitions far stranger than California or Oregon—from Canada to the Kamchatka Peninsula of Russia and even Syria after World War I. These weren't fever dreams of fringe politicians; they were serious diplomatic efforts involving presidents, congressional debates, and appeals from foreign leaders themselves who saw American annexation as preferable to rule by Mexi...

When St. Petersburg nobility mockingly called Moscow a "big village," in the 19th century – a time when they lived in all the excess found in a Tolstoy novel -- they couldn't have imagined the provincial fortress would become the heart of a nation spanning eleven percent of Earth's landmass and eleven time zones. It had a long warm-up time to get there. For nearly a millennium, Moscow has endured Tatar Mongols, Swedish armies, Napoleon, Hitler, devastating fires that never stopped burning even in snow and rain, and the Soviet destruction of its sacred churches—each catastrophe reinforcing the city's iden...

In the wake of Pearl Harbor, more than ten thousand Americans living abroad became trapped in Japanese-controlled territories, and with rumors of ill treatment and torture, the U.S. State Department was desperate to bring home its citizens. Despite the intense acrimony between the warring governments, a tireless State Department official, James Keeley, helped hatch an extraordinary plan through diplomatic back channels: each country would send a ship filled with civilians through war-torn waters to a neutral port city where their passengers could be safely exchanged.

Today’s guest is Evelyn Iritani, author of “Safe Passage: The Unto...

Emanuel Leutze's iconic painting Washington Crossing the Delaware shows the general standing heroically at the bow of his boat, staring toward an unseen enemy across the icy river. But who were those enemies waiting on the other side? They were Hessian soldiers from a small German state called Hesse-Kassel, forced conscripts sent to fight in a war they didn't understand, against democratic principles they were simultaneously being taught to admire back home. These men weren't the drunken barbarians of American mythology, but rather disciplined soldiers—many influenced by Voltaire and Enlightenment ideals—who fought in major battles from Long Isla...

For nearly two thousand years, swords reigned as humanity's weapon of choice—the first tools designed exclusively to kill other humans rather than hunt animals. When archaeologist Paul Gething rediscovered a rusty blade forgotten in a suitcase for thirty years, he unknowingly held one of history's most sophisticated weapons: a seventh-century Northumbrian sword so complex and finely crafted that only a king could have commanded its creation. The Bamburgh Sword tells the story of Anglo-Saxon England from 450 to 1066 AD, when feuding warlords wielded these pattern-welded blades with razor-sharp steel edges and bendy iron cores—weapons so precious they were cove...

Science progresses through breakthrough discoveries, but behind many of the field's greatest advancements lies a darker history of scientific dysfunction—hostile competition, information hoarding, and criticism that has silenced revolutionary thinkers. From Alexander Gordon being forced to flee Aberdeen after proving doctors spread deadly infections, to Ignaz Semmelweis being fired and exiled for insisting doctors wash their hands between autopsies and deliveries, brilliant scientists have paid devastating personal prices for challenging medical orthodoxies. The pattern repeats across centuries: Pierre Louis was attacked for using statistics to prove bloodletting was useless, Joseph Lister faced ridicule for suggesting "invisible germs" caused in...

In 1976, nine French wine judges did the unthinkable: they blindly selected two California wines over France's most elite vintages in what became known as the Judgment of Paris. This shocking upset sent shockwaves through the wine world and forever changed the global industry. French wine had dominated for centuries, built on a rigid classification system and prestigious terroir, but California winemakers like Warren Winiarski of Stag's Leap and Mike Grgich of Chateau Montelena proved that world-class wines could be produced anywhere with the right combination of climate, soil, and expertise. The tasting was organized by British expat Steven Spurrier...

Throughout the 16th century, one man stood between the Ottoman Empire and European domination, yet his name has been largely forgotten. Gabriele Tadino was an Italian military engineer whose genius transformed medieval warfare and saved Europe from one of history's greatest conquerors, Sultan Suleiman the Magnificent. In 1522, Tadino defied his Venetian masters by sneaking away in the night to defend Rhodes, where 700 Knights Hospitaller faced an impossible siege against 100,000 Ottoman troops. His revolutionary innovations—from acoustic devices using stretched skins and bells to detect enemy tunnels, to star-shaped fortifications that could withstand cannon fire—turned him into a legend amon...

America's Founding Fathers feared a standing army would inevitably threaten civilian governance. Yet 250 years later, the U.S. military remains a strange outlier among nearly every nation that has ever existed—maintaining its strength and popularity while never attempting a coup. How did America get this right when so many other nations, from Turkey to Latin America, have seen their militaries seize power?

The story begins with George Washington, who inspired mutinous soldiers to become the first army in a thousand years not to threaten democracy. But Washington's example alone doesn't explain America's success. Structural factors—dispersed urba...

Thomas Jefferson’s 1802 letter to the Danbury Baptists famously described the First Amendment as building a "wall of separation between church and State." This line has been the gold standard for those who point to the secular origins of America and the threat of funding any sort of religious activity. But this idea of America as a secular republic built on Enlightenment ideals misses a critical truth: Christianity has been at the center of American public life since European colonization began 500 years ago. The Constitution didn't create a wall between church and state—it inadvertently created a "free market" for...

There’s an argument to be made that every technology advance in communication – from cave paintings to fake AI movie trailers – is at its root an attempt to tell stories. Our first night-fires created the earliest audiences for spoken stories. In time, the development of rhyme, song, and other mnemonic devices allowed those spoken stories to be preserved for generations; pictures drawn on cave walls turned preservation into permanence, telling stories we still experience thousands of years later; writing enabled storytellers to spread tales to faraway places; the Chinese invented printing with moveable metal type around 700 AD; the Toltecs indepe...

During the Holocaust, Josef Mengele discarded every medical ethic to perform horrific human experiments at Auschwitz, including non-consensual vivisections, limb transplants, and agonizing surgeries conducted without anesthesia. Japan had its own program that is less known but equally brutal. In occupied China, the Imperial Japanese Army’s Unit 731 operated a vast complex where thousands were subjected to biological warfare tests and lethal physiological experiments to further military research.

During the occupation of Japan after WWII, the US had an important decision to make. Should they hold those responsible for atrocities during the war accountable or should they ta...

Since the era of Joseph Stalin, Moscow’s rulers have sent Russian athletes into the Summer and Winter Olympics with one command: you must win. These competitors operated under a "win-at-all-costs" doctrine most notably through the use of "shamateurism." By giving elite hockey stars nominal titles as military officers or factory workers, the USSR bypassed amateur requirements to field seasoned professionals against genuine Western students—a disparity that defined the Cold War sporting era. 

But the deception went deeper than employment records; it extended into the very biology of the athletes, particularly in high-strength disciplines like weightlifting and p...

Daniel Boone is considered one of the United States' first folk heroes for his exploration beyond the thirteen colonies into Kentucky. His exploits are rightfully legendary. He famously rescued his daughter and two other captives from Shawnee raiders by tracking them down on foot for three days. He survived a grueling ten-day siege at Boonesborough after escaping captivity by the Shawnee. Despite the frontier conflicts of the era between Indians and white settlers, he was so respected by his adversaries that he was formally adopted as the son of Chief Blackfish, cementing his status as a hero of the...

The most valuable shipwreck of all time is the San José galleon—an 18th century Spanish ship that carried 11 million gold coins, silver, and emeralds—and worth $20 billion in today's currency. It sunk in a battle with British ships during the War of Spanish Succession and remained completely lost for centuries. 
That is until a clue to its final resting place was found by the most unlikely  person: Roger Dooley, a Cuban-American underwater explorer who helped establish Cuba's national diving program and spent years scouring Caribbean waters for sunken shipwrecks at the behest of Fidel Castro. Dooley wasn’t looking...

America’s revolutionary war would have almost certainly been lost if not for the colony’s wealthiest merchant. Thomas Willing was a prominent Philadelphia merchant and financier who, in partnership with Robert Morris, operated one of the colonies' most successful importing and exporting firms, specializing in goods such as flour, lumber, tobacco, and sugar, while later using his wealth and mercantile connections to supply the Continental Army during the Revolutionary War.

After the War, he brought sanity to the unstable early American economy. America  was suffocating under a massive, unmanageable national debt owed to foreign lenders, domestic soldi...

Most of us only know Thomas Paine for one thing: writing Common Sense in 1776, which helped kickstart the Revolution by selling hundreds of thousands of copies. But he was far more than a writer. Paine actively served with George Washington's army during its darkest days and then used his pen to advocate for global freedom in both the French Revolution and against organized religion. His revolutionary fervor spanned the globe, leading him to champion the French Revolution with Rights of Man and challenge religious orthodoxy in The Age of Reason/

Paine's later involvement with the French Revolution...

Fad workouts have been with us for decades, but they go back much further than we realize. Long before CrossFit, Zumba, P90X, Tae Box, Jazzercise or Jack LaLanne, we had 19th century strongmen. These mustachioed showmen were the first global fitness influencers. They hauled trunks of weights onto steamships, toured the world, then sold exercise equipment through the mail. The most famous was Eugene Sandow, who broke chains, and created with his own body a "manned cavalry bridge" where he would lie down while men, horses, and a carriage were driven over his body. He even fought a lion...

In the eight decades since the United States deployed the most destructive weapon ever used, conventional wisdom has held that American leaders were faced with a difficult choice: Invade Japan, which would have cost millions of Japanese and Allied lives in bloody combat or use the fearsome atom bomb in the hopes of convincing the Japanese emperor to surrender. President Truman—in what many have come to regard as an immoral decision—ordered the military to drop the bomb.

Today’s guest is Alex Wellerstein, author of The Most Awful Responsibility: Truman and the Secret Struggle for Control...

National pride often comes from shared heritage—like a common language or ethnic background. Religious Nationalism can be seen in historical Russia, where being part of the Orthodox Church was considered key to being Russian, even if you spoke a different language, whereas Ethnic Nationalism is like modern Mongolia, where having the same Mongol background is what counts as national identity, even if people follow different faiths.—but for the small nation of Uruguay, that feeling of unity was forged not in a parliament, but on a soccer pitch. When the Uruguayan national team, La Celeste, stunned the world by w...

The wind-powered sawmill was invented around 1592 in the Netherlands, immediately transforming the nature of labor and industry. This mechanical marvel replaced slow, muscle-powered sawyers, allowing timber to be cut for shipbuilding and construction up to 30 times faster than manual labor, radically lowering the cost of wood products. It used a crankshaft to convert the windmill's rotating motion into the linear, up-and-down movement required for sawing wood, essentially creating an early, powerful assembly line factory. This mechanization allowed for unprecedented, rapid timber production, which quickly made the Dutch rich and enabled the massive expansion of their global fleet and construction...

We have paper money today because it functioned as an IOU, certifying that the holder could redeem it for an equivalent amount of physical gold or silver from the bank's vault. That’s where the English pound got its name as it matched a specific weight of gold (or silver). This was the gold standard, and this is how banks operated for centuries. But it was largely abandoned after World War I, when governments prevented the withdrawal of gold by suspending the convertibility of their paper money into gold to conserve national gold reserves for purchasing vital war supplies an...

Nearly a century of Cold War tensions between the United States and Russia hide the incredibly close friendship that the two nations enjoyed before this period. From America’s colonial founding in the 1600s to the eve of World War One, the two distant nations relied on each other in a surprising number of ways. Each country was searching for allies on the world stage, and this culminated in a "blueprint for friendship" during the 1860s and 1870s, spurred by mutual conversations around the abolition of slavery and serfdom. However, this amicable distance dissolved following the Russo-Japanese War, which in...

One of the worst nautical disasters in recent American history is the sinking of the SS Edmund Fitzgerald. On November 10, 1975, the “storm of the century” threw 100 mile-per-hour winds and 50-foot waves on Lake Superior. The ship found itself at the worst possible place, at the worst possible time. When she sank, she took all 29 men onboard down with her, leaving the tragedy shrouded in mystery for a half century.

The sinking of the SS Edmund Fitzgerald is so strange because the ship was exceptionally large and strong, and would normally be able to shrug off storms like this...

Over the course of World War II, Germany’s submariners sank over three thousand Allied ships, nearly three-quarters of Allied shipping losses in all theaters of the war. Winston Churchill famously declared the only thing that truly frightened him during World War II was the U-boat threat. But the treat was more imagined than real. The actual capability of the German Navy was somewhat limited. Some historians think that the Germans would have been better off in WWII if they had built no navy at all and devoted those resources to the army and the Luftwaffe. In the process th...

America’s growth from a rugged frontier nation to the globe’s industrial superpower in the space of 100 years can be explained by one word: coal. Before coal dominance, American buildings were defined by height limits imposed by stonework. The tallest building in the 1830s was Baltimore’s 235-foot tall Phoenix Shot Tower. Transportation also worked poorly without coal. The early wood-fired 4-4-0 locomotives struggled with top freight speeds around 15 mph and pulling trains of approximately 450 tons. The transition to coal and cheap steel enabled the steel-supported 555-foot Washington Monument and allowed massive coal-fired trains to achieve express passen...

For almost two centuries, Ancient Athens—the most successful democracy in history—selected citizens by lottery to fill government positions. Athens adopted sortition—a random lottery system—to select most public officials and the members of the Council of 500, a reform pioneered in 508 BC to break aristocratic control and distribute power equally among ordinary citizens. Some say it worked much better than the Assembly of Athens. In 406 BC, the Assembly rashly voted to execute all six victorious generals following a victory over Sparta because a storm prevented them from recovering the bodies of those who were lost at sea during a...

The "Madman Theory" was Richard Nixon's foreign policy strategy during the Vietnam War era, where he deliberately cultivated an image of being unpredictable and irrational—hinting he might escalate to nuclear extremes—to intimidate adversaries like North Vietnam and the Soviet Union into concessions. Nixon instructed aides like Henry Kissinger to spread rumors that he was volatile enough to "go crazy" and use drastic measures, hoping fear of his supposed madness would deter aggression and force negotiations without actual escalation.

Nixon's Madman Theory was relatively ineffective in coercing North Vietnam because Hanoi correctly gambled that the U.S. w...

The famous street artist Banksy shocked the art world in 2018 when his painting, Girl with Balloon, partially shredded itself moments after selling it for over a million dollars. at a Sotheby's auction in London. Banksy had secretly built a mechanical shredder into the painting's ornate frame, turning the destruction into a piece of performance art which was later authenticated and renamed Love Is in the Bin. He did this to make a statement about the art market's hyper-commercialization.

One of the most famous and influential philosophers of the ancient world enjoyed doing similar types of shocking stunts...

The greatest energy source for civilization before the steam engine was wind. It powered the global economy in the Age of Sail. Wind-powered sail ships made global shipping fast and cheap by harnessing free, reliable ocean winds to propel large cargo loads over vast distances without needing fuel or frequent stops. It also powered windmills, the factories of the Middle Ages and Renaissance. Windmills allowed for abundant bread by milling flour by turning heavy grindstones with wind-driven sails. They also powered trip hammers to forge iron and steel by lifting and dropping massive weights. We can credit them as...

Maps have always had problems. Five hundred years ago, maps were wildly inaccurate simply because cartographers were drawing the edge of the known world, limited by slow ships and nonexistent satellite data, resulting in continents that were too large, too small, or entirely misplaced. All of those problems have been solved thanks to new technology, but now there are new ones. Even though we know the exact dimensions of Earth, our maps are still "wrong" because we force a three-dimensional globe onto a flat surface, leading to mathematical distortions like the Mercator projection, which wildly exaggerates the size of...

In the 1800s, it seemed like mathematics was a solved problem. The paradoxes in the field were resolved, and even areas like advanced calculus could be taught consistently and reliably at any school. It was clearly understandable in a way that abstract fields like philosophy weren’t, and it was on its way to solving humanity’s problems. Mathematical work on electromagnetism made modern electrical engineering and power systems possible. New research in algebra created the logical basis for future computer science and digital circuits.

But then new problems appeared. In the early 20th century, mathematicians made disc...

The Battles of Lexington and Concord in April 1775, known as the "shot heard round the world," marked the first military engagements of the American Revolution. Ralph Waldo Emerson named it that because it launched revolutionary movements in Europe and beyond, marking it as a key moment in the fight for liberty and self-governance. But this moment was global in more ways than inspiring other nations. The quest for independence by the 13 North American colonies against British rule rapidly escalated into a worldwide conflict. The Patriots forged alliances with Britain’s key adversaries—France, Spain, and the Netherlands—securing covert arms s...

The brain acts in strange ways during wartime.  Even in active combat situations, when soldiers are one mistake away from death, many can’t fire on their enemies because their brain is triggering compassion centers against other soldiers. Studies of World War II show that while soldiers were willing to risk death, only 15% to 20% fired their weapons in intense combat, indicating a reluctance to kill. That’s why successful military leaders were able to motivate their soldiers with ideas of unfairness and justice, that their enemies weren’t human to make them better at fighting and killing.

All thi...

William F. Buckley Jr., the charismatic intellectual who defined modern American conservatism, was famously skilled at forging friendships across the ideological divide, a talent that helped him both shape the political landscape and navigate public opinion. His capacity for personal charm allowed him to be a public extremist and a private moderate, keeping him in the good graces of the liberal elite, including figures like Senator George McGovern and activist Allard Lowenstein, even as he worked to advance his conservative agenda; however, this magnanimity had its limits, most famously with his true enemy, Gore Vidal.

Today's guest...

The Collapse of the Soviet Union was twice as devastating as the Great Depression for those who lived there. It immediately led to widespread economic chaos and a breakdown of public services, plunging millions into a difficult period where mere survival was the priority. As one Russian described, after hyperinflation wiped out their family's savings, "my parents still had the same 50,000 rubles... But by then, all they could afford to buy with it was a pair of winter boots for my mother." There was optimism that democracy could emerge, but thirty years after the collapse of the USSR, the...

From Shakespeare's 'band of brothers' speech to its appearances in numerous films, Agincourt rightfully has a place among a handful of conflicts whose names are immediately recognized around the world. The Battle of Agincourt, fought in 1415, is famous for the decisive role of the English and Welsh longbowmen, who—despite being significantly outnumbered and exhausted—decimated the heavily armored French nobility with volleys of arrows. This unlikely victory was profoundly important because it not only paved the way for King Henry V to be named heir to the French throne via the Treaty of Troyes, but it also demonstrated the...

J.P. Morgan, John D. Rockefeller, and Charles E. Mitchell are names that come to mind when thinking of the most prominent icons of wealth and influence during the Roaring Twenties. Yet the one figure who has escaped notice is an enigmatic banker by the name of Clarence Dillon. In the 1920s, as he rose in wealth and influence, Dillon became one of the original behind-the-scenes players in Hollywood, and his contact list included everyone from Thomas Edison to Charlie Chaplin and Joseph P. Kennedy to FDR.

A revolutionary in finance, Clarence Dillon single-handedly created modern bankruptcy...

The American Indian leader Wakara was among the most influential and feared men in the nineteenth-century American West. He and his pan-tribal cavalry of horse thieves and slave traders dominated the Old Spanish Trail, the region’s most important overland route. They widened the trail and expanded its watering holes, reshaping the environmental and geographical boundaries of the region. They also exacted tribute from travelers passing along the trail and assisted the trail’s explorers with their mapmaking projects—projects that shaped the political and cultural boundaries of the West. What’s more, as the West’s greatest horse thief and...

Rome began as a pagan, Latin-speaking city state in central Italy during the early Iron Age and ended as a Christian, Greek-speaking empire as the age of gunpowder dawned. Everything about it changed, except its Roman identity. This was due to a unique willingness among Romans to include new people as citizens, an openness to new ideas, and an unparalleled adaptability that enabled Romans to remake every aspect of their society in ways that made it stronger and more resilient. Romans, who believed that their city was originally settled by exiles and captives, found a balance between the embrace of new...
